TWO'IWHEEILED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 365,812, dated July 5', 1887.

Serial No. 237,708. (No mod cl.)

To all whom it may concern:

Be it known that I, BYRON J. HEALY, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, and State of Michigan, have invented a new and useful Two- \Vhccled Vehicle, of which the following -is a specification. y

This invention relates to the ordinary style of two-wheeled vehicles, having a body or seatbars supported over the axle and fulcruined to the thills or cross-bar at the forward end.

The object of the invention is to adj ustabl y attach the spring to the body or seat-bars by means of a chain or other flexible connection or equivalent, set forth below. Other objects will appear in the description.

Both sides of the vehicle are like the side here shown.

Referring to the letters marked on the drawings, D is the seat-bar or bodyfulcrumed to the thill B and suspended over the axle A, substantially as heretofore. The spring r is attached to the axle A, and has an upwardlyextended end provided with r a slot, 1), and notches a. The upper end of the slot 1) is enlarged to. allow the chain to pass through. The slot 11 is narrow, and the chain a is inserted flatwise of its link, and the rear link prevents the chain drawing out, and the notches u prevent it from working up or down. The other end of the chain is attached to the body forward of the axle. Thus when the body' swings down it draws on the chain and contracts the spring. By drawing the rear end of the chain farther through the slotted end of the spring r, and catching the link or another link in a lower notch of the spring, the spring and body are adjusted for heavier persons. The adjustment may be effected by hooking the forward end of the chain a in the desired one of a series of holes in an upwardly-inclined row in bracket 2, Figs. 1, 4, and v5. The bracket may be attached to a laterally-ex tending bar, 0, Fig. 2, or directly to the body, Fig. 6. The laterally-projecting bar a is not new with me; neither is it new in this application to coil the spring around the axle. If preferred, the spring 1" may be located obliquely to the plane of the axle, as in Fig. 6, so as to attach the forward end of the chain directly to the seat-bar D or body, and as the chain is flexible a correct strain will be had upon the spring when the body swings up and down.

Fig. 5 shows how a rod, a, may be employed as an equivalent in some respects to the chain, from the fact that the loose or jointed attachment atboth ends gives the rod a flexible action.

When desiring to test the speed of the horse, it is frequently desirable to rigidly support the bodythat is, not have it elastically supported. I accomplish this by detaching the end of the chain a from the spring 1" and attaching it directly to the axle A, Fig. 4., or other suitable support. It is obvious that various styles of springs may be employed in this adjustable relation with the chain; but -I have found the style here shown works very satisfactorily.

of the spring may have hooks or projections to attach the chain to, and the bracket 2' may be thus constructed as well.

Fig. 4 illustrates what may be done in case a spring should break, in order to support the body temporarily.

Having thus described my invention, what I claim is- 1. The combination of thebod y, the axle, and the springs having the upwardly-extending free ends with the chains attached to the body, thence extending rearwardly, and dctachabl y and adj ustably connecting'with said free ends of the springs, whereby the length of the chains between their end attachment may be readily increased and diminished, substantially as set forth.

2. The combination of the axle, a body or seat-bars, springs having the slotted notched end, and chains or suitable flexible connections between the body or seat-bars and the slotted end of the springs, substantially as set forth.

Ofcourse, if preferred, the end' 3. The body provided with the side brackets having an inclined row of adjusting-holes, springs having free ends, and flexible connections between said body-brackets and the free ends of the springs, substantially as set forth. 4. The combination, substantially as set forth, of the axle, a body or seat-bars fulcrumed at the forward end, springs located obliquely to the plane of the axle,'and flexible connections between the free end of said springs and the body or seat-bars, substantially as set forth.

5. The combination of the axle, a body or seat-bars fulcrumed at the forward ends,

springs mounted upon the axle and having the 1 5 free ends, and chains attached to thebody or seat-bars and detachably attached to the free end of the springs, whereby the use of the springs may be dispensed with and the body sustained by the chains, substantially as set 20 forth.

In testimony of the foregoing I have hereunto subscribed my name in presence of two witnesses.
